为了证明char占用4字节,我们可以通过以下代码示例来演示: publicclassCharSize{publicstaticvoidmain(String[]args){char[]chars=newchar[1];chars[0]='a';System.out.println("Size of char array: "+chars.length*2+" bytes");}} 1. 2. 3. 4. 5. 6. 7. 8. 在这段代码中,我们创建了一个char类...

That's all about the 8 essential data types in Java. It's must for every Java developer to not just know about these data types but also how and when to use them. You should also know what are their size like how many bits or bytes they take to store values as well as what are...
In terms of range, a byte variable can hold any value from -128 to 127 but a char variable can hold any value between 0 and 255. Another difference between byte and char in Java is that the size of the byte variable is 8 bit while the size of the char variable is 16 bit. One...
